Speeificationof Application, filed July 10,

To all "Lulu/m. it may concern: p

Be it known that I, BRUCE Fonn, a citizen .of the-United States, andresident-ofPhiladelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Storage-Battery Plate, ofwhich the following is a specification.

Objects of the present invention are to ob tain in a simple andcomparatively inexpensive manner the advantages of a laminated wall orwall consisting .of superposed thin plates for retaining the activematerial and affording access for the electrolyte thereto and to providecomparatively inexpensive and reliable means for holding such retainingwalls to place.

In the accompanying drawings, Figure 1, is a side View of a storagebattery plate embodying features of the invention. Fig. 2, is asectional view taken'on the line 22 of lfig. 1. F ig. 3, is a sectionalview illustrating a modification of the invention, and Fig. 4, is asimilar view illustrating another modification.

The plate comprises a suitable frame 1, containing a grid of conductingmaterial.

Referring to Figs. 1 and 2, the bars 3, are of H-shape in cross section.On each side of the body of the arms there is active material ormaterial to become active 4, and the ends 1 of the arms. are turned inso'as toretain walls 5 cons1st1ng of piles of thin sheets-or laminae.

The sheets may be of hard rubber and their thickness maybe likened tothat of paperi They are piled one upon another and the electrolyte maycirculate between them, but they efiiciently retain the active material.

As shown in Fig. 3, the bars 6, of the grid are of H-shape, incross-section, and active material or material to become active 7, is

arranged on opposite sides of their body arts. The active material ofadjacent bars is held to place by a laminated wall 8, consisting ofwasher-like rings or sheets piled one i uponanothera In this casethelaminated walls are heldito place by and between adjacent bars.

As shown in Fig. 4, the bars 9, are of I- shape in cross section andactive material or 1 material to become active 10, is placed u on eachside of their bodies. The sheets t at Letters Patent. I Patented May 11,1909.

walls of thin sheets are held in'contact with the conducting walls ofthe receptacles. What I claim is:

conducting grid having open faced receptacles for active material ormaterial to become active, active material or material to become activearranged in the receptacles, and laminated retaining walls consisting ofpiles of thin sheets covering the open faces and active material andclamped by the conducting 'alls of the receptacle, substantially asdescribed. 2.
